Abstract (en)
A ring (11) for a fine spinning machine is used in the fine spinning machine for winding a yarn through a traveler (12) sliding on a sliding surface of the ring (11) in a dry state. The sliding surface of the ring (11) is covered by chrome plating (13). In the chrome plating (13), a ratio of emission intensity of hydrogen atoms (H) to emission intensity of chromium atoms (Cr) determined by glow discharge optical emission spectrometry (GD-OES) is 0.1 or more.
